Application filed November 22, 1889i Serial No. 331,202. (No model.)

1'0 all whom it may concern:

Be it known that I, REUBEN BITTER, a citizen of the United States,residing at Philadelphia, in the county of Philadelphia and State ofPennsylvania, have invented certain new and useful Improvements inLubricator Attachments and I do declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame, reference being had to the accompanying drawings, and to theletters of reference marked thereon, which form a part of thisspecification.

This invention relates to lubricators, and aims to provide a device thatcan be readily attached to a bottle or other vessel for ejecting thelubricant onto the part to be lubricated.

The improvement consists of the novel features which will be hereinaftermore fully described and claimed, and which are shown in the annexeddrawings, in which- Figure 1 is a side view, parts being broken away, ofthe attachment, showing its applicasion to a bottle. being broken away,of the attachment. Fig. 3 is a cross-section on the line X X of Fig. 2,looking in the direction of the arrow.

The barrel A is provided with the spout or nozzle 13 and with thetubular extension 0, which project from diametricallyopposite sidesthereof. The extension C is integral with the barrel and isscrew-threaded to form a positive and close connection with the vesselto which the attachment is applied. The spout or nozzle B is preferablyseparate from the barrel, being connected therewith by screwing it onthe threaded nipple a, which is provided on the said barrel.

Fig. 2 is a side view, parts The plunger D, a tubular section, fits thebarrel snugly and is held normally at the ex treme outer limit of itsmovement by the spring E, which is placed within the barrel between theplunger and the closed end of the barrel. This tubular section is closedat each end, the inner end forming the compression-face and the outerend the thumb or finger rest, and is limited in its movements andprevented from turning in the barrel by the pin h, which passes throughthe slot 6 in the sides of the tubular section and has its ends seatedin the sides of the barrel.

The attachment is applied by inserting the extension 0 into a suitableaperture provided in the cork of abottle or in any desired vessel. Apressure on the outer end of the plunger .forces it into the barrel andexpels the oil.

WVhen the pressure is removed, the spring E returns the plunger to itsnormal position In testimony whereof I afliX my signature in presence oftwo witnesses.

REUBEN BITTER.
